Study on Performance of Transverse Flux Permanent Motors

Based on the study of the torque and power factor equations, this paper proposed a new view on the characteristic of the transverse flux permanent machines. By introducing the electrical-magnetic loading and flux weakening vector compensation, it is noted that the higher phase MMF, more flux leakage and unique configuration is the key causing the performance of high torque and low power factor. The method gives clear expression and useful techniques to improve the performance of TFPM, and would be as the constructive principle in machines design and control.
